想知道下列英语句子语法有没有错误（求指导）

Question

After looking out the window for hours, I found the rain passed.

Answer 1

首先说有语法错误。looking out window 应为 looking out of window，look out是不及物动词短语，后边不能接宾语，而这句话的意思是：我透过窗户向外看了几个小时/我向窗外看了几个小时，所以要用look out of。

Answer 2

out 后再加一个介词of
After looking out of the window for hours, I found the rain passed
